FILE - In this March 3, 2015 file photo, Defense Secretary Ash Carter, left, accompanied by Joint Chiefs Chairman Gen. Martin Dempsey, testifies on Capitol Hill in Washington before the Senate Armed Services Committee. Iran’s growing influence in Iraq is setting off alarm bells, and nowhere is the problem starker than in the high-stakes battle for Tikrit. It marks a crucial fight in the bigger war to expel the Islamic State group from Iraq, and yet Iran and the Shiite militias it empowers _ not the U.S. _ are leading the charge. Carter, under questioning from Sen. John McCain this week, acknowledged his concern when McCain asked if it alarms him that Iran “has basically taken over the fight.” (AP Photo/Manuel Balce Ceneta, File)
